    This is a REPL OpenAPI3 description document text editor. It provides both a CLI and and a REPL you can use to
    test your APIs, but you can also test database queries, start and stop database (containers), generate fake data
    automatically, start your test microservice and much more. You don't have to exit from your REPL! Or you can use
    the CLI to do the same if you want, giving you the option to automatize your contract-first based dev cycles.
